Black Diamond Carpentry & General Contracting — Westford, MA | Tavlee

Black Diamond Carpentry & General Contracting is a one-person shop in Westford run by Ryan Sullivan, and the state registry backs the credential that matters most for structural work: Construction Supervisor licence CS-079065 is recorded as active in his own name. The company's own account of itself is unusually specific. It says the business was founded in 1990 by Ed Buckingham, that Sullivan started full time in 1992 after graduating Lowell Vocational High School, passed the Construction Supervisor exam in 1998 while a Journeyman Carpenter, and took the business over in 2002, renaming it Black Diamond Carpentry & General Contracting. The Better Business Bureau, which opened its file in December 2002, records the business as a sole proprietorship with one employee and grades it A+, though it is not a BBB Accredited Business. The work is residential remodeling and finish carpentry: additions, kitchens and bathrooms, finished basements, porches and decks, built-in cabinetry, stairs, doors, windows and hardwood floors. The company says its scope runs from a few replacement windows up to 400-1,500 square foot additions, and that it stays inside Westford and the towns around it. Two things are worth pinning down on a first call. The supervisor licence on file expires on 4 October 2026, so confirm it has been renewed before work starts on anything structural. And the sources disagree about how long the business has been going — the company's site says 1990 and the BBB record says it was established in Massachusetts in 1992 — so ask directly rather than relying on either figure. There is no published customer review record anywhere: BBB carries none, and no directory or Google review corpus exists for this row. That means the honest read here rests on the licence, the BBB grade and the company's own account, not on other homeowners' experience. It suits someone who is comfortable asking for references directly and who wants a licensed supervisor personally on the job rather than a crew.
